Black Star, the duo of Yasiin Bey and Talib Kweli, stopped by the set of Late Night With Jimmy Fallon last night two perform a pair of tracks with some help from The Roots. They chose to tackle "You Already Knew," off their upcoming Aretha Franklin tribute project, and "Little Brother," a cut off the soundtrack for 1999's The Hurricane. The latter also paid homage to J Dilla, who produced the track and passed away nearly six years ago. You can watch them perform "You Already Knew" above while "Little Brother" is below.
